Abstract (en)
[origin: US5305410A] The present invention provides a dielectric optical fiber cable which is capable of being remotely detected while buried. Specifically, this invention incorporates magnetic materials into existing superabsorbent tapes which are commonly used to provide water-blocking capabilities in nearly all optical fiber cables. One embodiment of the present invention includes a tape which has been treated with a blend of neodymium iron boron and superabsorbent powders.
